Middy Posted October 20, 2016 Share Posted October 20, 2016 I suppose I am in an even smaller group as I know nothing but trying to copy improvements at cost.....I wouldn't know an oscilloscope from silly string.... Capacitive Coupling is 2 fat people in a small room having sex.....[emoji15] But I keep trying so thanks for the links..much appreciated as always Dave?

Cornan Posted October 20, 2016 Share Posted October 20, 2016 Here is my finalized test cable! The tubing of the Supra ground wire is a bit special (couples with the shield) so I had to cover it with electrical tape to minimize interfearences. Not pretty... but the sound is pretty though! First impression is very good with a more natural flow and clearer notes in comparison with my Audioquest NRG2 cable. Definately something I will persue with a properly done cable. I will go right ahead and order better parts and make it a final cable! This is the competitor that will be collecting dust from now on: Sent from my Nexus 7 using Computer Audiophile mobile app 🎛️ Audio System Link to comment
Middy Posted October 20, 2016 Share Posted October 20, 2016 Lovely my friend....nice... With that configuration you could try a tri twist to see the effect. We need to start giving a marking system how we judge the changes..... From my Lapp cable off a real to just common power cable.... As a base line of 0 This gets a +2 ... My version will try 2 solid and a multi core earth....... Spaced out... I saw they have hollow pins on the Mapleshade connector but I wonder what the purpose and material of the loose plastic is on the wires are? Keep up the good work Dave Sent from my SM-G900F using Computer Audiophile mobile app Link to comment

Keep up the good work Dave Sent from my SM-G900F using Computer Audiophile mobile app Thanks Middy! Hollow connectors should mean less resistance & higher impedance...so that would be a very interesting plug to use...atleast for my cable were the whole point is less capasitive coupling (=less resistance & higher impedance) and a cleaner ground connection. I know Entreq is using similar ideas on their IC's but actually not on their AC cables were they use Furutech plugs. Do let me know if you find any Schuko plugs with hollow pins! Difficult to give rates on DIY projects. I can only say that my test cable beats Supra Lorad 2,5 MKII and Audioquest NRG-2 hands down which is quite good cables in my point of view. I would'nt know how they hold up against much better cables...which I have'nt heard in my own system and will not buy or cannot afford anyway! My AC cable holds true to my vision of how it should be/should sound and the SQ is just great...and that means everything to me!

esldude Posted October 20, 2016 Share Posted October 20, 2016 Indeed. Solar panel manufacturing have the same problems: Solar Energy Isn’t Always as Green as You Think - IEEE Spectrum [/OT] Did you read the article? So it might take a solar cell 4 years to make up for CO2 used in producing it. That if it is installed where electricity produces less CO2 than somewhere like China. Okay, so the next 20 or so years thereafter you are coming out ahead. One day solar power can be used to produce new cells and that will look even better. The other items like protecting workers from chemicals is an issue with virtually all industries. Nothing special about solar in that regard. So as a negative about solar cell production, use and green-ness color me rather unbothered. One way or another eventually future electricity will be solar or nuclear for many reasons. And always keep in mind: Cognitive biases, like seeing optical illusions are a sign of a normally functioning brain. We all have them, it’s nothing to be ashamed about, but it is something that affects our objective evaluation of reality. Link to comment

Every day is a school day...... learn learn learn Sent from my SM-G900F using Computer Audiophile mobile app To me personally it all makes sense thinking about the capasitive coupling as the root of all evil for good SQ. To remove everything that adds capasitive coupling were possible will grant you a better sound. Same "law" applies to electronics. IMO all cables should be an Autobahn for signals & power and not limited by impedance or resistance, ie. make them short and make them clean and quick! Opposite to many other on this forum I personally refuse to believe that impedance matching does anything good for the sound. It only limit the cables IMHO. However, using for example unshielded wires needs attension to distance between ALL wires in the system. Best method to shield something from a distrubing source is to move it away from the disturbence. Were this is not practicly possible it is best to ground the shield to a separate and clean grounding point...or as last option to send it straight to the safety ground (which could/would end up in your system through the backway). Anyway, next up will be to make a good DC cable with separated positive and negative wires! 🎛️ Audio System Link to comment

However, I think you forgot one of the "rules" though. Keep the unshielded wires short. It needs to be <50cm to limit RFI/EMI. Also make sure it is on a safe distance from other cables by atleast >4 times the diameter of the thickest cable.

Also make sure it is on a safe distance from other cables by atleast >4 times the diameter of the thickest cable. Sent from my Nexus 7 using Computer Audiophile mobile app If you only need a mains cable <50CM long, you would be better off chopping a normal 3 core mains cable to that length, and fitting another IEC female plug. As my DAC is quite close to the filtered powerboard in the cabinet I have done that. Also consider cables like the attached wherever possible. http://www.altronics.com.au/p/p8417-powertran-0.5m-iec-c13-10a-3-pin-black-appliance-mains-lead/ P.S. If the device being powered via that cable (above) is powered by an SMPS you may find that it will act like an antenna and radiate RF/EMI !

Middy Posted October 21, 2016 Share Posted October 21, 2016 The cable was just cut the same length as my Lapp shielded cable..Now its in my bedroom both these cables are too long by far....But wanted some parity in comparison..... It will get chopped back but that is as much practicality as experimental...... I still have the "it's wire from the power station" mentality..... So changes to sound still baffles me..... The Mapleshade style will be the next try using the same 2.5mm solid cable.. I do try with an open mind and no expectation....... I am just a cheap B*stard. .... trying things.... Thanks for the advice both...? Sent from my SM-G900F using Computer Audiophile mobile app Link to comment
Cornan Posted October 23, 2016 Share Posted October 23, 2016 Actually, after pulling my new cable in and out a couple of times comparing it to my Audioquest NRG-2 it is a bit edgy...so I will likely try to twist the Neutral & Live to see if it improves. It still performance better with transparency and natural flow...but is a bit lighter and harscher overall. Further test needs to be done before making it a final cable I guess...

YashN Posted October 23, 2016 Share Posted October 23, 2016 so I will likely try to twist the Neutral & Live to see if it improves. Probably the first thing that should have been done.

Cornan Posted October 23, 2016 Share Posted October 23, 2016 Well, twisting the Live & Neutral (but still GND on a distance) did make a big difference. Much better overall. Improved 3D sense to it all and easier to follow background details. Nothing lost from previous gains which I can hear so far...but will give this a couple of days before I switch back to my Audioquest NRG2 again for another comparison.

Cornan Posted October 23, 2016 Share Posted October 23, 2016 Can't really move away from disturbances which are all around you... That's why I suggested other options as well in the same post! Shielding connected to ground sucks the life out of the music IMO (makes it dull)...but it can be improved if it is connected to external ground. YMMV ofcourse!

Middy Posted October 24, 2016 Share Posted October 24, 2016 looking at the Mapleshade cables. .. I just noticed thier twists are doubles... Hot neutral is next for me.. but it looks like they have 2 live neutral twists and 2-4 single earth's. ...It could be 1 live 2 wires twisted and 1 neutral 2 wires twisted but the wire colours are mixed so hard to tell without looking inside...... So many designs......Can't wait to try a twist cable..... Cheers Dave Sent from my SM-G900F using Computer Audiophile mobile app Link to comment

So many designs......Can't wait to try a twist cable..... Cheers Dave Sent from my SM-G900F using Computer Audiophile mobile app It is a bit difficult to understand Mapleshades AC cable. Looking at this picture... ...it looks like you´ve said that the neutral and live are twisted separately....and not together. It also looks like there is a separate ground wire and a separate neutral ground/drain wire...but I cannot tell how they are connected in the IEC plug on any other pictures. Neutral is actually connected to ground in the AC mains network so there could be a clue there. I´ll surely need to look for more clues to understand their concept to the full...but it looks like a very intresting approach that I also would like to try out...as soon as I understand it! Edit: Reading on their website they describe it rather as two "outrigger" ground wires (ie. both connected to ground)...and most likely their twisted cables are live+neutral twisted x 2. A pity they do not have these cables with schuko plugs. I would´nt mind buying them since they are not that expensive when checking how much a DIY version with good quality plugs and wires would add-up to. 🎛️ Audio System Link to comment
Cornan Posted October 24, 2016 Share Posted October 24, 2016 I think I might ask Mapleshades if they can make them with Schuko plugs and deliver to Sweden. As a second option I found this adapter... ...but still need to ask them if their cables would work trouble free with 240v. 🎛️ Audio System Link to comment
